SPECIFICATION forming part of Letters Patent No. 478,277, dated July 5, 1892,

Application filed February 29, 1892. Serial No. 423,179. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK W. FIEDLEE,

a citizen ot the United States, residing at Scranton, in the county ot' Lackawanna and State of Pennsylvania, have invented a new and useful Hub, of which the following is a specification.

This invention relates to vehicle-wheels; and it has for its objectto provide animproved hub for vehicle-wheels constructed of comparatively few parts and in suoli a manner that in the event of -a spoke breaking a new one can be substituted without taking oft' the rim of the wheel or disturbing the other parts of the wheel atall, and one which is also so constructed that a worn-out or broken axle-box can be readily replaced without interfering with the other parts of the wheel.

It is also intended by this invention to pro- Vide a sectional hub which when connected together will tend to force the spokes toward the rim of the wheel, which point is of essential importance when replacing new spokes into the wheels.

qWith these and many other objects in View, which will readily appear as the nature ofthe invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

In the accompanying drawings, Figure l is a vertical sectional view of my improved hub. Fig. 2 is a similar view of the parts dissembled and illustrating the method of inserting spokes therein. Fig. 3 is a detail in perspective of the rea-r mortise-carryinghub-section. Fig. 4 is a detail'sectional view of one of the spoke-mortises and spokes.

Referring to the accompanying drawings, A represents an axle-box interiorly tapered to accommodate the ordinary axle B and eX- teriorly tapered, as at C, the inner half of its length, While the other halt` is exteriorly threaded, as at D. The said axle-box A is further provided with the inner collar E, and directly in front of said collar is a projecting lug orstop-pin F, which prevents the axle-box from turning in the hub, to be described. The rear solid hub-section G is provided with a tapered bore to snugly tit the inner tapered portion of the axle-box, and is provided with the inner recessed shoulder g, taking over the collar E of said axle-box, and is further provided within said shoulder with the notch or recess g', receiving the locking-lug F, which prevents thevinnerhub-section from turning on the axle-box or the axle-box turningin said hub-section. The inner solid hub-section G is further provided with an integral eXteriorlytapered ange I-I,which forms a continuation of the inner bore of said hub-section, and la tapered base for'each one of the radial series of receiving-mortises I formed on said hubsectiou directly over the eXteriorly-tapered iange H. The said mortises are designed to receive the tenons J of the spokes K, which tenons are provided with lower beveled ends j, which are inclined to correspond with the exterior taper of the integral flange H, forming the base ot the mortise in which the spoketenon is inserted. When inserting the spokes of the wheel in the first instance or replacing new spokes when the old ones have become broken, the outer ends of the spokes are first inserted in the felly and then the beveled tenons thereof laterally inserted into one of the mortises I as far as it can be placed b v hand, asillustrated in Fig. 2. The front solid hub-section L is now placed in position. The said solid front hub-section L is provided with an iuteriorly-threaded bore M, which engages the eXteriorly-threaded outer end of the axlebox A, and with a fiat inner face N, which as the said section is screwed in position over the threaded end of the axle-box will contact with the projecting edges of the tenons of the spoke or spokes just ,inserted and force the same tightly into the mortise and, on account of the bevel thereof, outwardly toward the folly, whereby the said spoke or spokes are tightly forced in position and the entire wheel braced. The eXtreme outer end of the axlespindle B receives the ordinary binding-nut O, which irnpinges against the outer ends of the front hub-section and the axle-box to hold the same in position upon the axle, while at the same time being partly concealed from view and out of the way.

It is thought that it can be readily seen that` the various parts ofthe herein-described hub can be removed without disturbing the other parts, whereby broken spokes can be readily replaced without taking ott the rim of the wheel, by simply unscrewing the front of the hub and taking out the broken spoke and replacing it, as already described; also, a Wornont axle-box can be easily replaced without disturbing the wheel. This is only accomplished by the few-parts employed in constructing the hub and the manner in which the same are assembled.

The construction and many nses of the herein-descrbed hub are now thought to be apparent without further description. At this point it is well to observe that the walls I of the mortises I have their upper ends beveled or inclined at the same angle to correspond With the bevel of the iiange H, which receives the lower beveled ends j of the spoketenons. It is of course understood that the shoulders j of the spoke-tenons rest upon the top of the mortise-Walls I', and in order to insure a perfect fit when the spoke-tenons are inserted in said inortises the said shouldersj are beveled correspondingly to the top beveled or inclined ends rof said Walls.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

In a hub, the combination, With the axle, of the axle-box having its rear half exteriorly tapered and its outer half exteriorly screw threaded, the rear hub-section having an exteriorly-tapered bore fitting the rear half of said axle-box and provided with a projecting exteriorly tapered or inclined flange, and a radial series of mortses arranged over said flange, which forms the base for said mortises, the solid front hub-section having an exteriorlythreaded bore engaging the threaded halt' of said axle-box and a fiat inner face Working over the open edges of the mortises, and a securing-nut engaging the outer threaded end of the axle-spindle and bearing directly against the outer end of the axle-box and the outer face of the front hub-section, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aiixed my signature in the presence of two Witnesses.

FREDERICK YV. FIEDLER.
